Dear Doctor, I Live In Croatia, But I Have An

Dear doctor,

I live in Croatia, but I have an interesting health condition for which I am not able to get an explanation:

I am 54 years old and I was diagnosed with rheumatoid arthritis a year ago.
I had terrible "moving" pains: one day my ankle hurts that I can't use my leg at all, the next day my wrist hurts so much that I can't use my hand ... and so on)
Laboratory findings:
CCP = 59.2 kU / l (ref int <5)
Rheumatoid factor: 41.7 IU / ml (ref int 0-14)

I immediately started taking Mettotrexate but my pain did not decrease. I'm taking it now also.

But I got a cold and used higher amounts of vitamin C. The pain vanished. I continued to drink vitamin C to the limit when I got diarrhea and it was over 20 grams of vitamin C !!!!

So, I now continuously take 15-20 grams of vitamin C daily and have no pain at all.

Interestingly, a few months ago my sister (aged 62) also got rheumatoid arthritis, but it was located on her ankles.
She does not drink vitamin C and about 10 years ago most of her teeth fell out.
(She did not suspect a lack of vitamin C because she pays attention to her diet and takes it in the recommended amounts)

I'm looking for advice:
do we have a genetic predisposition to make very little use of vitamin C so we need to take mega doses to achieve a “normal” vitamin C concentration in the body?
Do we need larger amounts of vitamin C because inflammatory processes "eat" it?

Should I take vitamin C intravenously?

Could rheumatoid arthritis have occurred due to vitamin C deficiency?

Please opinion and advice
Kind regards!
